The invention discloses a high-voltage interlock detection system, method and electric vehicle. The system is applied to electric vehicles, including: high-voltage components, high-voltage connectors, high-voltage interlock detection modules and vehicle control units; high-voltage interlock detection modules correspond to high-voltage components; high-voltage components include high-voltage interlock detection input ports and high-voltage The interlock detection output port; the high-voltage connector is used to electrically connect two high-voltage components; the high-voltage interlock detection module includes a low-voltage signal source and a detection unit, the low-voltage signal source is electrically connected to the high-voltage interlock detection input port, and the input terminal of the detection unit is connected to the high-voltage interlock detection input port. The high-voltage interlock detection output port is electrically connected, and the output end of the detection unit is electrically connected to the vehicle control unit; the detection unit is used to detect whether the connection of the corresponding high-voltage components is normal and generates a corresponding detection result; the vehicle control unit is used for According to the detection result, it is judged whether the electric vehicle is powered off. The system can quickly check the fault point of the high-voltage interlock and improve the maintenance rate.

The invention provides a monitoring method and a monitoring system based on a mobile terminal. The method comprises the steps of detecting the movement condition of the mobile terminal; detecting the service condition of the mobile terminal for a user; if the movement condition shows that the mobile terminal has movement information, and the service condition indicates that the mobile terminal has at least one piece of contact information, use distance information, use angle information and use information in eyeball use information of the user, starting risk warning. According to the method and the system provided by the invention, detection accuracy on service condition of the mobile phone for the user can be improved, and accurate warning is achieved.

The invention discloses a smoke alarm control method based on computer processing and system thereof, relating to the field of smoke sensor. The smoke alarm control method includes that during the debugging, the smoke sensor acquires the environment smoke values and sends the values to an environment test module, the environment test module detects the environment to obtain the environment intrinsic state; the smoke sensor acquires environment smoke data and sends the smoke data to a value weight mean value processing module, the value weight mean value processing module calculates the smoke weight mean value (as shown in the description); the smoke alarm solution module determines whether the smoke value of the current environment is in a dangerous state based on the smoke weight mean value (as shown in the description) and the environment intrinsic state; and if the smoke value is in a dangerous state, a controlled relay is pulled in or disconnected. The invention further discloses a smoke alarm control system based on computer processing. The smoke alarm control method can improve the accuracy of smoke alarm and prevents smoke false alarm or error alarm.
